Plasma patterning of carbon nanotubes

We have prepared micropatterns of carbon nanotubes on a wide range of subst rates either by patterned growth of aligned nanotubes on surfaces prepatter ned with plasma polymers (e.g., n-hexane plasma polymer) or through region- specific adsorption of certain chemically modified carbon nanotubes (e.g., -COOH substituted nanotubes) onto surfaces prepatterned with various plasma -generated functionalities (e.g., -NH2). Micropatterns of carbon nanotubes prepared in both cases have resolutions on a micrometer scale, suitable for fabrication of various electronic and photonic devices.
